I Need Help

Hello!
My name is Aaliyah. I am 23. I was adopted by my grandparents when I was 2 months old. They've raised me without any help from my biological parents. In 2016, my freshmen year of highschool, I lost my grandfather to Alzheimer's.
I took it insanely hard. I was one of the only ones he remembered in the end. I had reoccuring dreams where he would walk in the door and tell us that he's actually alive, and that he still loves us. They would feel so real, and then I'd wake up.

Now, in 2026, my grandmother is suffering from Lewy body dementia. It has been so much worse than Alzheimer's was for my grandfather. She is forgetting me. She doesn't remember her oldest kids. She is violent. She hallucinates. She has been refusing medicine and isn't eating. Her husband and I took her to the hospital, where she got transferred into a geriatric behavioral hospital to get her medicine sorted to return home. I am so scared for her. I just know she is scared right now. I feel awful that's she's even there and that I cannot do more for her. I work full-time, go to school full-time, and I have two young boys under 2. I know I am going to regret not making the sacrafices I need to be there for her, but I know I won't survive if I don't continue to work for myself and my kids. This isn't fair. When I look at my mom, I see her. She is beautiful, but the light is drawn out of her eyes. It's like she's not really there. She speaks, and it's not her talking. I wish I could take all this away from her and give it to myself.
